To all whom it may concern:

Be it known that l, DAVID L. PnNRoD, a citizen of the United States, residing at Hooper, in the county of `Weber and State of Utah, have invented new and useful Amalgamating Mill, of which the following is a specification.

This invention aims to provide novel means for ainalgamating metals, the construction being such that the metals will be subjected thoroughly to the alnalgarnating substance, novel means being provided for conveyingl the amalgamating substance fromthe bottom of the structure to the top thereof.

It is within the province of the disclosure to improve generally and to enhance the utility of devices o-f that type to which the invention appertains.

With the' above and other objects in view which will appear as the description proceeds, the invention resides in the combination` and arrangement of parts and in the details of constructionhereinafter described and claimed, it being understood that, within the scop'e of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the .spirit of the invention;

1n the accompanying drawings t Figure 1 shows in side elevation, an apparatus constructed in accordance with the invention. parts being in section; Figure 2 is a vertical longitudinal section; Figure 3 is an end elevation, parts being broken away; Figure`4 is a section showing one of the receptacles and attendant parts; Figure 5 is a `section on the line 5-5 of Figure 1; Figure 6 is an elevation showing the distributorzfand Figure 7 is an elevation showing a modified form of distributor.

In carrying outI the invention there is provided a support, denoted generally by the numeral 1, and including a base 2 and a framefri on the base. The numeral 4 marks a baille carried by brackets on the frame 3, the-baffle 4 discharging into a baffle 5, the batlle dischargingr into a baille 6. The baffle 6 discharges into a baffle 7, the baffle 7 discharging into a baille 8, the baffle 8 communicating with a baille 9 which, in its turn, discharges into a baffle 10, the baffle 10v discharging into aI baille 11 communicating with a baffle 12, the several Abaffles being downwardly inclined and being supported on the iframe 3. The baffles 5, 6, 7, 8, 9, 10, 1l and 12 `are closed at one end, as shown at 14, and each bafe has an inclined lip 15 dis charging upon the baille neXt therebeneath. The crushed ore is delivered to the baffle 4 through a chute 16 mounted on the frame 3. The baffle 12 discharges into a basin 17 formed in the base 2, or constructed otherwise, the basin having an incline 18.

A shaft 19 `is journaled on the frame 3 at the intake end of the bafiie 4, a shaft 20 being ournaled on the baille 4 at the discharge end thereof. A shaft 21 is" journaled on the frame 3 and is located at the discharge end of the ba'liie 5. A shaft 22, similarly supported, is located at the discharge end of the baille 6. A shaft 23 is journaled on the frame 3 and is located at the discharge end of the baffle 7. At the discharge end of the balile 8 there is a shaft 24. A shaft 25 is disposed at the discharge end of the baffle 9. A shaft 26, journaled on the frame 3 is located at the discharge end of the baflle 10. A sh aft 27, likewisej ourn aled on the frame, is located at the discharge end of thebaflle 11. At the discharge end of the baffle 12, there is a shaft 28, journaled on the frame 3. A shaft 29 is journaled on the frame 3 and is disposed at the outer end of the basin 17. A shaft 30 is journaled on the upper portion of the frame 3, in approXimate horizontal alinement with the shaft 19. The shafts 19, 20, 21, 22, 23, 24, 25, 26, 27 and 28 carry respectively, sprocket wheels 31, 32, 33, 34. 35, 36, 37, 3S, and 39. Sprocket wheels 41 are mounted on the shaft 29. The shaft 30 carries sprocket wheels 42. A sprocket wheel 43 is located externally of the frame 3, as shown in Figure 1 and is mounted on the shaft 24. A conveyor is provided, including chains 44 and blades 45 projecting both upwardly and downwardly ,from the chains. The said conveyor is adapted to move along the bottoms of the bafes`4, 5, 6, 7,8, 9, 11 and 12 and is carried by the sprocket wheels 31, 32, 33,. 34, 35, 36, 37, 38,

4.o, 4i and 4.2.

The power shaft 46 is journaled on the y baffle 10 or on any accessible portion of the frame 3 and carries a pulley 47 or other suitable means for driving the shaft, the pulley 47 being engaged by a belt 48. There is a sprocket wheel 101 on the shaft 46, the sprocket wheel 101 driving av sprocket chain y49 engaged about the sprocket Wheel 50 on a shaft 51 j ournaled on the baffle 10 or on any accessible portion of the frame 3. The shaft 51` carries a sprocket `wheel 52 engaged by a sprocket chain 53 cooperating with the sprocket wheel 43 on the shaft 24.

It will be obvious that the conveyor 44-45 is actuated from the power shaft 46 by a train. including the sprocket wheel 101, the sprocket chain 49, the sprocket wheel 50, the sprocket wheel 52, the chain 53, the sprocket wheel 43, the shaft 24 and the Sprocket wheel 36.

First tanks 54 are formed in. the base 2 or are constructed otherwise. The numeral 55 designates second tanks located in advance ot' the first tanks 54. The tanks 54 and 55 are connected by conduits 56. Conduits 57 lead from the basin 17 to the tanks 55. A shaft 58 is journaled on the trame 3 above the tank 54. Shafts 59 and 6() are journaled on the upper portion oij' the traine 3,. The shaft 58 has sprocket wheels 61 and.

there are sprocket wheels 62 on the shafts 5.9 and 60. Conveyors 63 are engaged with the sprocket wheels 61 and 62 and include buckets 64 adapted to dip in the first tank 54. A sprocket wheel 65 is mounted on the shaft 58 and is engaged by a sprocket chain 66 cooperating with a sprocket wheel 67 on the power shaft 46. The conveyors 63, therefore, are driven 'from the power shaft 46 by the sprocket wheel 67, the chain 66, the sprocket wheel 65, the shaft 58 and the sprocket wheels 61. y

Upper receptacles 68 are llocated out* wardly of the frame 3 at each side thereof, the receptacles 68 being provided with depending outlet tubes 69 connected to a distributor 70, which may have an elongated slot 71 discharging into the uppermost baffle 4. The receptacles 68 are supported on brackets 103 mounted on the upper portion of the frame 3. If desired, the distributor 72 of Figure 7 may be substituted i'or the distributor of Figure 6, the distributor 72 being provided with spaced perforations 73. The distributors 70 and 72 are of tubular form.

A shaft 74 is journaled on the base 4 and is located above the second tank 55. The shaft 74 carries a sprocket wheel 75 engaged by a chain 76 cooperating with a sprocket wheel 77 on the power shaift 46 The shaft 74 is provided with sprocket wheelsl 78. Shafts 79 and 8O are ournaled onr the frame 3 and are located above the baiiic 12. The shafts 79 and 8O are provided with sprocket wheels 81. About the sprocket wheels 81 and 78 is trained a conveyor 82 havingr buckets 83 adapted' to dip into the second tanks 55. Lower receptacle 84, constructed like the upper receptacles 68 is located at the sides of the Jframe 3 and are provided with outlet tubes 85, connected to a transverse. tubular distributor 86 discharging); into the baffle 12 constructed like the `distributor72. p

In praoticaloperation, the crushed ore is 'delivered into the baiiie 4 through the chute 16, and, moves downwardly along the batfles 5, 6, 7, 8, 9, 10, 11 and 12, into the basin 17, under the impulse imparted to the ore by the conveyor 44-45. Since the blades 45 oit the conveyor project both upwardly and downwardly with respect to the chains 44 the lower edge of each blade 45 advances the ore along one baille, say the baiile 4, and, then, when the ore is in another baiiie, say the bai'lie 5, the conveyor is inverted, and what were formerly the upper edges of the blades now advance the ore. The crushed ore is drawn out of the basin y17 by that portion of the conveyor 44-45 which moves between the sprocket wheels 41 and the sprocket wheel 40.

The buckets 64 on the conveyor 63 scoop the amalgamating` substance, generally mercury, out of the tanks 54, and carry the mercury upwardly, the mercury being discharged from the buckets 64 into the upper receptacles 68. From the upper receptacles 68, the mercury traverses the outlets 69 and moves into the distributor 70, the mercury passingr from the distributor upon the ore which is moving along the uppermost bafiie 4. Obviously, by the time that the ore has moved downwardly alongr the baiiie, the ore, or more specifically, the particlesA of t.gold or other metal which have been pressed out of the ore, will be mingled thoroughly with the mercury.

The buckets 83 dip the mercury out of the second tank 55 and carry it upwardly, and discharge it into the lower receptacles 84, the mercury passino; from the receptacles 84 through the outlet tubes 85 into the distributor 86, an additional charge ofmercury being` delivered upon the metal, just as the metal is movingr out ot' the lowermost baiiie 12. The surplus mercury, if any, iowingir 'trom the battle 12moves into the basin 17 and settles to the bottom of the basin. Since the bottom of the basin 17 is downwardly and rearwardly inclined, i,as shown at 18, the mercury flows through the conduits 57 back into the second tanks 55,

and from the second tanks 55, the mercury Hows to the first tanks 54 through the conduits 56.
